| Core Tip |
Hepatic perivascular epithelioid cell tumors (PEComas) are very rare. This is the first review to investigate and compare the results of both PEComa and epithelioid angiomyolipoma patients. As PEComas are primarily benign tumors, surgical interventions may be avoidable. The key findings in the differential diagnosis of this tumor include a blotchy vascular pattern within the tumor and no hemorrhage within tumors less than 7 cm at the maximum diameter. Furthermore, if PEComas have hemodynamic features similar to those of hepatic angiomyolipomas, then the patterns of the drainage veins would very likely be useful for differentiating hepatocellular carcinomas from PEComas, as observed in our case. |
